What is Example Of Open Circuit Impedance?

Determine the open-circuit impedance parameters of the network of Fig. a.

FIG.

SOLUTION

For convenience, we draw the network of Fig. a as shown in Fig. b.

Here Z1 = R1 || 1/sC1 = R1×1/sC1/R1+1/sC1 = R1/1+sR1C1

Z2 = R2, Z3 = Z

By KVL in the left-hand mesh

V1 – Z1I1 – Z1(I1 + I2) = 0

V1 = (Z1 + Z2)I1 + Z2I2

Also V1 = z11I1 + z12I2

By comparing these equations we get

z11 = Z1 + Z2 = R1/1+sR1C1 + R2

And z12 = Z2 = R2

By KVL in the right-hand mesh

V2 – R1I1 – Z2I2 – Z2(I1 + I2) = 0

V2 = (R3 + Z2)I1 + (Z2 + Z3)I2

Also, V2 = z21I1 + z22I2

By comparing these equations we get

z21 = R3 + Z2 = R3 + R2

z22 = Z2 + Z3 = R2 + Z
